The Innovation： Low-latitude forcing: A new insight into paleo-climate changes

Main text

The origin of glacial cycles is central to paleo-climate research. A major breakthrough of Earth science in the 20th century was the discovery of orbital forcing of the glacial cycles, known as the Milankovitch theory. The periodicity of the glacial cycles over the last million years was successfully explained by the variations of June solar insolation at 65°N. In responding to the changes in the Arctic polar ice sheet driven by insolation, the production of the North Atlantic deep water drives the global climate changes through the “great conveyer belt” of the global ocean. Despite the unsolved problems embedded in the theory, it has become accepted wisdom in paleo-climatology.
